In addition to the Florida panther, there are three moderately sized terrestrial carnivores in South Florida: the bobcat, and two canines, the gray fox and the recently re-naturalized coyote.
There are several introduced mammals in South Florida. Two are common enough to be of ecological significance: the black rat and the domestic pig.
Most native mammals are of widespread distribution in North America. Common examples include the Virginia opossum, gray squirrel, common raccoon, northern river otter, gray fox, and whitetailed deer. Other examples of widespread species that are present but now uncommon in South Florida are the short-tailed shrew, black bear, eastern fox squirrel, mink, and panther. Other common mammals are species widespread in the southeast coastal plain, such as the marsh rabbit, cotton mouse, hispid cotton rat, and marsh rice rat. A regional pattern observed in several mammals is the occurrence of subspecies in the Florida Keys that have probably evolved very recently, after isolation by rising sea level. Examples are the Key Largo cotton mouse, Key Largo woodrat, lower keys marsh rabbit, and key deer.
